request to set `_R_CHECK_TESTS_NLINES_=0`

This would print out all the output lines in case of test failure. Sometimes the stack trace is quite lengthy and just 13 lines of it (a default value) doesn't help much. This diverges from the default a little but I feel there is a value for package maintainers. Alternatively, this could be a very big number (1000?) to avoid some extreme case. I'm interested in hearing your thoughts on this.

Are you aware you can see all the install/test logs by clicking underneath the check output in the GHA logs?

Yes. This is what I'm referring to. On test failure, rcmdcheck reports only last 13 lines of output. This is not very actionable. An example: https://github.com/r-universe/pharmaverse/actions/runs/8882670125/job/24388015743 (highlighted the part telling about 13 lines of output)

I mean underneath the check log, you can expand the full log files:

Yes. This is what I need. Thanks for pointing this!
